Question

A wire is bent in the shape of a square of side 66cm. If the same wire is looped in the form ofa circle, what will be the radius of the circle?(Take pi=3.14)

Answer 1

As the circle and square is made of wire of same length therefore

perimeter of circle=perimeter of square
2πr=4×side
2πr=4×66
2πr=264
πr=132
3.14×r=132
r=132÷3.14
r=132×1/3.14
r=42.03






hope, it helps
